Synonymous with longevity, quiet strength and serenity, the 32,000-odd trees that make up our urban forest are not only a key part of our garden city’s unique cachet, they also contribute to our collective well-being.

The Town has dedicated itself to preserving this green heritage: learn more!

Our arboreal heritage is there to see

Aware of the unique role that trees play in our community and keen on addressing the worrying issue of climate disruption, Town Council adopted its second Tree Policy in 2017. In particular, the policy aims to provide a better framework for preserving our urban forest. Read it to learn more about the environmental importance of trees.

Give a tree to your community

Whether to mark the passing of a loved one, the arrival of a newborn or simply to contribute to the Town’s green heritage, trees can be donated to the municipality.

Through the Tree Donation Program, the Town will handle the planting and maintenance of trees free of charge.

Want to cut down a tree? Check the by-law first.

A tree may be cut down in certain situations:

  • The tree is dead or has contracted an incurable disease.
  • The tree poses a risk to the health or safety of citizens.
  • The tree prevents construction, use or landscaping that complies with municipal regulations and has been approved by the Town. Trees may not be cut down in order to allow the installation of a sign or to make the sign more visible.

For more information, see chapter 9 of Zoning By-law No. 1310 regarding landscaping (French only). In all cases, a tree-cutting permit is required. Contact the Urban Planning and Inspection Division by email or phone (514 734-3042) to learn how to proceed.

What to do with your branches?

An pick-up of tree and shrub branches is available on request from April 1 to September 30.

Emerald ash borer: measures to limit its spread

The emerald ash borer has constituted a problem in urban forests for several years now. To limit the spread of this insect pest within its borders, the Town has implemented an action plan in addition to adopting By-law No. 1433 on April 27, 2015.

Do you own an ash tree? Have it treated with TreeAzin.

Effective for two years after application, TreeAzin is a preventative treatment that should be administered to all ash trees with trunks more than 10 cm in diameter. 

This year, the Town will once again reimburse 50% of the cost of treatment, provided you agree to use the services of the Town’s official supplier, Bio-Contrôle Arboricole.

Period authorized for processing: June 14 to August 27
Price: 3.49$/cm diameter + taxes

Procedure for obtaining the grant

Call the Town's inspector at 514 734-4222 or by email at:, to arrange for your ash trees to be evaluated. The inspector will guide you through the process by providing advice adapted to your situation. 

The request for treatment must be sent directly to the inspector as soon as possible. The request will be forwarded to the Town's official supplier, who will perform the work by the required deadline. 

If your ash is infested by the borer at a rate of 30% or more, it must be cut down.

Before cutting down any ash tree 10 cm or greater in diameter, you must apply for and obtain a permit to cut down a tree on private property. The permit is issued free of charge.
